Abstract
The invention discloses a rolled black rubber outsole rubber for liberation shoes. The outsole rubber is characterized by comprising the following components in parts by weight: 70 to 90 parts of standard rubber, 10 to 30 parts of cis-butadiene rubber, 40 to 50 parts of highly wear resistantcarbon black, 4 to 8 parts of zincoxide, 1 to 3 parts of stearic acid, 0.5 to 0.7 part of promoter M, 1.6 to 2.0 parts of promoter DM, 0.4 to 0.6 part of promoter D, 0.8 to 1.2 parts of anti-aging agent RD, 0.8 to 1.2 parts of anti-aging agent DFC-34, 5 to 7 parts of industrial fat, 10 to 12 parts of coumarone, 110 parts of calciumcarbonate, 1.6 to 2.0 parts of sulfur, and 5 to 7 parts of pine tar. 70 to 90 parts of standard rubber with a very good adhering force are used, the outsole rubber has a very good adhering performance therefore, and can be used for a long time under intensive movements, and the glue failure will not happen. Coumarone and pine tar, which have an excellent adhering performance, are used, thus the outsole rubber has a very good adhering performance. The adhesion force and adhesiveness between the edge glue and the libration shoes prepared from the outsole rubber are high, and the service life of liberation shoes is largely prolonged.
Description
technical field [0001] The invention relates to the field of rubber material preparation, relates to a formula of outsole rubber for shoes, in particular to a calendered black rubber outsole rubber for Jiefang shoes. Background technique [0002] The outsole rubber used for Jiefang shoes has a high requirement for bonding with the sponge rubber in the midsole of the shoe and the adhesive glue brushed on the upper of the shoe, and requires high tear strength to adapt to high-intensity activities and Exercise to ensure that the side glue and the outsole are not glued, degummed, or separated from the edge. Especially for labor-type Jiefang shoes, the combination of the surrounding strip rubber and the outsole rubber is insufficient due to the insufficient adhesive force of the existing outsole, and the adhesion force is less than or equal to 2.2kN / m, and the glue often occurs during wearing and moving. , causing water to enter the shoes, making them uncomfortable to wear, and ...
